Yes it is, I'm getting 4200/400 on my desktop. Thinking of upgrading to the 802.11G router to get a better signal down stairs and and on the opposite side of the house from the router,my adapter is a G series.
Thanks,comcast just upgraded our speed so I'm happy. I use a Linksey router #BEFW11S4 and a wirelees b notebook adapter #WPC54G.Did some tweeking through DSLReports.
